Hi Carlos, John nccmp built for me with the following:export LDFLAGS="-L/my/netcdf/4.1.3/gnu-4.4.7/lib -L/my/hdf5/1.8.11/lib "; ./configure --prefix /my/nccmp/1.4.0; make; make check; make install
The NetCDF library above was built with the corresponding HDF5 library. It also worked without any LDFLAGS plus NetCDF 4.1.1 and HDF5 1.8.5-patch1 installed from packages (via yum). In both cases the computer is x86_64 Linux CentOS 6.4.Somehow it failed with NetCDF 3.6.3 ( undefined reference to `nc_inq_dimids') and
4.3.0 (make check, segmentation fault). I guess nccmp requires NetCDF-4. 'make check' only works if the PATH and LD_LIBRARY_PATH point to the same NetCDF installation above. I hope this helps, Gus Correa On 12/10/2013 01:16 PM, John Caron wrote:
Hi carlos, im forwarding this to netcdfgroup@xxxxxxxxxxxxxxxx which deals with the netcdf c library.

Checking the documentation, the installation follows the typical structure: ./configure make make check make install make clean However, I'm stuck in the first step because the configure is not able to find my netCDF libraries. But I don't know why. My libs are not in the default folder, I've installed them in /opt. But I've included the path of the netCDF libs in my LD_LIBRARY_PATH variable. I tried also to create a link in the default lib folder to my netCDF libs ln /opt/netcdf-4.2.1.1/lib/libnetcdf.so /usr/lib/libnetcdf.so ln /opt/netcdf-4.2.1.1/lib/libnetcdff.so /usr/lib/libnetcdff.so ln /opt/netcdf-4.2.1.1/lib/libnetcdf.a /usr/lib/libnetcdf.a ln /opt/netcdf-4.2.1.1/lib/libnetcdff.a /usr/lib/libnetcdff.a But it doesn't work either. I explicitly used the path in the call ./configure --libdir=/opt/netCDF/ I set LIBS and LDFLAGS to LDFLAGS=-L/opt/netcdf-4.2.1.1/lib/ LIBS=/opt/netcdf-4.2.1.1/lib/ and execute configure then, but with the same bad results: checking for nc_open in -lnetcdf... no configure: error: in `/opt/nccmp': configure: error: Required NetCDF library not found! In the config.log I see: configure:3763: gcc -o conftest -g -O2 conftest.c -lnetcdf -lm >&5 /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libnetcdf.a(libnetcdf4_la-nc4file.o): In function nc4_rec_read_types': /opt/NETCDF_BUILD/netcdf-4.2.1.1/libsrc4/nc4file.c:1850: undefined reference toH5Gget_create_plist' and many more similar lines like that one... I don't know what else to try, so any help would be really appreciated.
